The research carried out under this contract includes assisting in the data analysis fro the Prognoz-9 _Nssion, linking results of the computer codes to the Prognoz-9 data library in order to study the spectral shape and evolution of cosmic gamma-ray burst energy spectra, and using the results of this study to help to determine or constrain the physical conditions at the gamma-ray bursts sources. The results of this work led to several publications that have shed considerable insight into the gamma-ray burst mystery, and gives a new diagnostic for determining the nature of gamma-ray burst sources. The outcome of this work also provides a new specmd form for studying the temporal evolution and spectral behavior of gamma-ray bursts.
